Bunker Quantity Surveys

Bunker Quantity Survey (BQS) – Ensuring Transparency, Compliance & Accuracy

Independent Verification. Precise Measurement. Industry Compliance.

Bunker Quantity Surveys (BQS) are essential for ensuring fair, accurate, and compliant bunker fuel transactions. At Seahawk Services, we provide independent fuel quantity measurement and sampling, ensuring that both buyers and suppliers receive transparent and dispute-free deliveries. Our BQS follows internationally recognized standards, including:

✔ SS648:2024 (Singapore MPA Standard)
✔ ISO 13739 (Petroleum Measurement Standards for Bunker Fuels)
✔ ISO 8217 grade (Marine Fuel Quality Standards)
✔ MARPOL Annex VI Compliance

Why Choose an Independent Bunker Quantity Survey?

✔ Prevents financial loss – Confirms the actual quantity delivered, avoiding overcharges.
✔ Ensures representative sampling – Verifies fuel quality with proper sampling methods.
✔ Reduces disputes – Immediate resolution of discrepancies during bunkering.
✔ Enhances regulatory compliance – Meets MPA Singapore SS648:2024, ISO 8217:2024, and global standards.

💡 With fuel costs increasing, even minor discrepancies in bunker quantity can have a significant financial impact. Independent verification ensures accuracy and prevents costly claims.

Seahawk Services BQS Process

Our certified BQS surveyors oversee the entire bunker operation, ensuring precise quantity measurements, compliance with SS648:2024 mass flow metering requirements, and accurate fuel sampling.

📌 Pre-Bunkering Procedures

Communicate with vessels, suppliers, and agents to coordinate a smooth operation.
Review fuel delivery details – including fuel grades, delivery method, and receiving vessel requirements.
Verify the use of SS648:2024-compliant Mass Flow Meter (MFM) systems, ensuring proper calibration.
Confirm sampling procedures – ensuring compliance with ISO 8217:2024, MARPOL Annex VI, and MPA guidelines.

🛢 Fuel Quantity Measurement (SS648:2024 Compliance)

Monitor bunker delivery using approved mass flow metering systems in SS648:2024-compliant ports.
Conduct manual tank measurements before and after bunkering when MFM is unavailable.
Verify barge, truck, or terminal fuel quantities to detect discrepancies.
Oversee the entire bunker operation, immediately addressing any quantity disputes.
Perform ROB (Remaining On Board) inspections to account for undelivered fuel.

🧪 Fuel Quality Verification (ISO 8217:2024 Standards)

Ensure proper sample collection methods – including drip, continuous, or spot sampling.
Secure fuel samples with tamper-proof seals and documentation.
Verify compliance with ISO 8217 grade fuel specifications as required by customer, including:

Sulfur content & emissions compliance
Viscosity & ignition properties
Catfine levels for engine protection
Water, sediment, and contamination levels
Cold flow properties (pour point, wax appearance/disappearance temperature, CFPP)

Verify supplier-provided fuel samples to ensure alignment with delivered fuel.
